Description
Params (Source, Type, Sense, Masking) and CGT (Clip, Gain,
Transparency) to the values saved for Fill-2/Key-2
UNLOAD INPUT
Unloads the keyer input, either media from a store or external fill/key

LOAD IMAGE
Loads a file from the image library into the appropriate store
SET POSITION
Sets the screen position of an image or animation.

SET KEY PARAMS
SOURCE
SELF
[4.8.5.1] Key data is derived from the Fill signal
SEPARATE
[4.8.5.1] Key data is derived from Key signal
NONE
[4.8.5.1] Key data is set white so there is no transparency
TYPE
FULL
[4.8.5.3] Passes the foreground signal where the key signal is present
LINEAR
[4.8.5.3] Sums background and foreground images to create the signal
SENSE
NORMAL
[4.8.5.4] Selects the mode in which a black key means transparent and a
white key is opaque
INVERT
[4.8.5.4] Selects the mode in which a white key means transparent and a
black key is opaque
MASKING
DISABLE
[4.8.5.5] Uses no masking of the keyer output
SETUP
[4.8.5.5] Defines a mask area within the range determined by the size of
the image and the standard.
C, G & T
[4.8.5.2] Sets Clip, Gain and Transparency. Clip is the level under which
the key signal will be forced to black. Gain amplifies the signal forcing
grey levels to approach white. Transparency affects the luminance of the
key and therefore the amount of background allowed in the output.
